dc.description.abstractIntoxication by dispersion of glyphosate droplets in coffee seedlings is common and, in addition to the problem of drift, there are reports of contamination of this herbicide to a nontarget plant via the rhizosphere. Hydroponics allows the comparison of the translocation of the glyphosate absorbed by the foliage or the roots and avoids the interaction with the soil, which could hamper the achievement of more accurate conclusions when it is absorbed by the root. Thus, the toxicity of glyphosate sublethal dosages in the initial growth of coffee plants in hydroponics was evaluated by applying four sublethal dosages in two different locations (solution and leaf). Fifty days after the application of the herbicide, the intoxication percentage and the growth of the coffee seedlings were evaluated. From the reduced dose of 115.2 g·ha-1 of glyphosate, height reductions, root length; number of leaves, dry mass of leaf, roots and total, leaf area, and leaf mass ratio were observed. The first two parameters were observed only in leaf application and the others via leaf and solution. The aerial part–root ratio system had an increase in herbicide sublethal dosages when applied to leaves and the ratio of leaf area and specific leaf area increased in both applications. Sublethal dosages of glyphosate applied to young coffee plants under hydroponic conditions impair their growth, and it is more accentuated with increasing doses and when the leaves, instead of the roots, absorb the herbicide.pt_BR
